Using the USB Host Mode

This embedded application source code illustrates how to implement a simple USB host application with CDC support. In the host mode, the USB can be connected (with a mini A connector attached to the mini AB EVK110x receptacle) to a standard CDC device (or another EVK110x running device CDC application). The controller will initialize and enumerate a device CDC application.

In our example, we will connect 2 EVK110x boards together using the USB: one will act as a host, the second one will operate as a device. Connect the USART output of each board to the COM ports of a PC (e.g. HyperTerminal under Windows systems or minicom under Linux systems; USART settings: 57600 bauds, 8-bit data, no parity bit, 1 stop bit, no flow control).

Open the 2 terminals using the same baudrates.

The following picture shows the architecture of the host application:
